9. Determining Quantity Based on Doses, Pills, or Capsules .—If the number of doses, pills, or capsules but not the weight of the controlled substance is known, multiply the number of doses, pills, or capsules by the typical weight per dose in the table below to estimate the total weight of the controlled substance ( . , 100 doses of Mescaline at 500 milligrams per dose = 50 grams of mescaline). The Typical Weight Per Unit Table, prepared from information provided by the Drug Enforcement Administration, displays the typical weight per dose, pill, or capsule for certain controlled substances. Do not use this table if any more reliable estimate of the total weight is available from case-specific information.
Because a good history and physical examination are very good at picking up shoulder rotator cuff issues, I typically do not initially get an MRI of a shoulder I’m trying to treat non-operatively. I use MRI’s when the diagnosis is in doubt or for pre-surgical planning. If the patient had a violent trauma with a lot of shoulder dysfunction, I might get an MRI in that setting, as acute rotator cuff repair for a complete tear would be reasonable. Likewise, if the patient is an overhead athlete with months of shoulder pain before I see them, I might get an MRI or even an MRI arthrogram (where dye is injected into the joint), to look for a SLAP tear (tear of the labral cartilage), which can occur with internal impingement.
